AWS FreeRTOS, ESP32, WOVER-ethernet-kit v1.1 uninitialized variables ....

First off, I do have the esp32 default FreeRTOS working, but the requirement has come down from the requirements god, that I must use the latest FreeRTOS from Amazon. So I know I have the toolchain all setup properly etc.

My hardware is the ESP32-Ethernet-Kit_A_V1.1

I have been following the instructions here:
[https://docs.aws.amazon.com/freertos/latest/userguide/getting_started_espressif.html]

darkLightning:esp stv$ git clone https://github.com/aws/amazon-freertos.git

I am on the latest stable code from the repo which from the README is the release branch. So I do the following:


git clone https://github.com/aws/amazon-freertos.git

Checking out files: 100% (13609/13609), done.
darkLightning:esp stv$ cd amazon-freertos/

Then I switch to the release branch (NOTE: I didn’t upgrade the submodules, because it doesn’t seem that the release branch likes that )


darkLightning:amazon-freertos stv$ git co release
Branch 'release' set up to track remote branch 'release' from 'origin'.
Switched to a new branch 'release'

Now edit things like the doc said. And run the python setup, after editing the file


darkLightning:amazon-freertos stv$ vi tools/aws_config_quick_start/configure.json
darkLightning:amazon-freertos stv$ cd tools/aws_config_quick_start
darkLightning:aws_config_quick_start stv$ python SetupAWS.py setup

And then build the makefiles…

 

darkLightning:amazon-freertos stv$ cmake -DVENDOR=espressif -DBOARD=esp32_wrover_kit -DCOMPILER=xtensa-esp32 -S . -B build

And then I do the make all -j4

Then I thought it could be a -j4 think, so without it I get …

Any ideas on how to fix this I’d appreciate it. I’m hesitant to touch the code because this “should” works as it’s the stable branch.

What is the version of your ESP32 compiler? You can check that using the following command:


xtensa-esp32-elf-gcc --version

The latest version of the ESP32 compiler does not work with ESP-IDF version in Amazon FreeRTOS and you need to make sure that you get the ESP32 complier as mentioned in the “Setting Up the Toolchain” section here: https://docs.aws.amazon.com/freertos/latest/userguide/getting_started_espressif.html

Which OS are you running on and what is the CMake version are you using?

I tried building the release branch on Ubuntu 18.04 using the following commands and it worked for me:


git clone git@github.com:aws/amazon-freertos.git
cd amazon-freertos/
git checkout release
cd ..
cmake -DVENDOR=espressif -DBOARD=esp32_wrover_kit -DCOMPILER=xtensa-esp32 -S . -B build
cd build/
make all -j4

My ESP32 toolchain version:


xtensa-esp32-elf-gcc (crosstool-NG crosstool-ng-1.22.0-80-g6c4433a) 5.2.0

My version of the compiler was wrong. I have another issue but I’m going to start a new thread for that as this issue is resolved. I had to go to the AWS “how to page” and go to the MacOS link. It points to the proper toolchain.
